NGK Racing Spark Plugs

What’s firing your engine? NGK racing spark plugs are built to withstand the severe mechanical and thermal shock associated with high-revving, high-compression engines. NGK racing plugs feature special electrode materials—precious metals like platinum, iridium, and ruthenium—for greater durability and low voltage requirements. Fine-wire center and ground electrodes provide better sparking and enhanced ignitability. And, the unique arrangement of insulator noses improves throttle response!
